Decay measurement according to VDA 19.1 & ISO 16232

Validation and verification of extraction efficiency for residual contamination analyses according to VDA 19.1, ISO 16232, as well as OEM and customer-specific testing requirements.

What is a decay measurement?

Decay measurement is used to verify the extraction efficiency in residual contamination analyses.

Through repeated extractions, it is demonstrated that the selected test method adequately captures the particles present on a component and yields reproducible results.

Why is a decay measurement necessary?

✅ Verification of extraction efficiency

✅ Validation of new test procedures

✅ OEM and customer specifications

✅ Ensuring reproducible results

✅ Procedure compliant with VDA 19.1 and ISO 16232

Typical application areas

• New components

• New assemblies

• Product modifications

• New extraction procedures

• Customer-specific requirements

• OEM approvals

Execution at TecClean

Depending on component geometry, material, type of contamination, and customer requirements, we develop suitable extraction procedures
and validate them using decay measurements.

The results are documented and can serve as a basis for future serial inspections.
